00 — Overview

What the ESD5Z2.5 does

The ESD5ZxxT1G series are micro-packaged transient voltage suppressor diodes designed for ESD protection in space-constrained applications like cellular phones and portable devices. This family spans working peak reverse voltages from 2.5 V to 12 V, including variants such as the ESD5Z2.5T1G through ESD5Z12T1G. Key parameters include a clamping voltage typically under 15 V, a peak power dissipation up to 240 W, and a response time faster than 1 ns. These components offer an ESD rating of 16 kV per the Human Body Model and feature low leakage current. Engineers typically use them to safeguard voltage-sensitive components from electrostatic discharge and transient voltage events in digital cameras, power supplies, and other portable electronics.
